PNEUMATIC VEHICLE-TIRE.

Specification of Letters Patent.

Patented April 21, 1908.

Application filed May 20, 1907. Serial No. 374,567.

To all whom it may concern:

Be itknown that I, MARY B. PRIEST, a

Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Pneumatic Vehicle-Tires;-and I do hereby declare that the following is a full, clear, and exact descr lipltion thereof. i

e object of my invention is to provide a non-puncturable pneumatic-tire for vehicles, the construction and arrangement bein such, that by a combination of rubber and metallic-rings the tread or shoe-portion of the tire, when striking an obstruction will be wheel-rim, the rigidity of the tread thus formed, renders the supporting area of theload upon said tire approximately half its diameter, in place of a few inches, as is the case with pneumatic tires having the cornmonly-constructed soft treads, thus making it possible to dispense with the high air-. pressures required in sustaining a load.neces-, 1

tires LI'G used. The inventiontherefore consists in various peculiarities of construction and combination of parts as hereinafter fully set forth with re erence to the accompanying drawings and subsequently claimed.

11 the drawings: Figure 1 represents a cross-section of a tire emb'odyingthe features of my invention, the tire being, formed with beads adaptable to attachment to rims of the clencher type, the section being indicated by line 11 of Bi. 2 Fig. 2, an elevation of a portion of t e same with parts broken away-Hand parts in sectlon'to better illustrate the invention, and Fig. 3, a detail cross-section of a portion of the tire illustrating means forprotecting the edges of said tire against puncture. Referring by letter to the-drawings, A indicates a one-piece pneumatic tire-casing formed preferably with a greater width than height, the side-walls of which tire-casing The inner-face of the oneiece tire-casing is flattened and has roecting beads B, which beads are fittedinto the inturned edges of' a metal-rim C, and

held'therein by the usual method of stay the bottom of said grooves an thereby effectually seal said joint ing split for the insertion of the usual innertu The outer-face of the. tire-casing is pro-l In a pneumatic vehicle-tire com having flexible side- 0 vided with a flat-tread E, over which is fitted a metallic-band H serving the double purpose of adding rigidity and preventing puncture of the air-com artment.- The tread is further provided wit annular grooves F, and

a series of cross-grooves G, together with cross-wires a, embedded therein at intervals throughout the circumference of said tread, the cross-wires terminating flush with the edges thereof.

A thick liable shoe E composed of rubber is adjusted to the metallic-band, which shoe is provided with annular side-grooves F similar to those of the tread and likewise cross-wires b, the of said tread serving to stiffen the arts.

The shoe together with the meta lie-band is held against lateral motion by means of metal side-rings I, which rings have inturned flanges 0 adapted to fit the annular grooves of the 5 casing-tread and outer shoe, clamped to the sides of the by bolts 12 that grooves G, snugly said rings being res ective parts pass through the crosstting the s ace between the metallic shoe. The bolts, as shown, are upset'against the vertical outer faces of the side-rings I, serving to thus hold the assem-, bled parts securely together, saidringspractically transforming the tread-portion 0f the 35 tire into a rigid rin adapted to yield in its entirety in a vertioa directionwith relation to. the wheel-rim proper through the medlum of interposed air carried bythe flexible portion v I of said tire.

From the foregoin seen that the rings overlap the joint between the tread-portion of the casin proper, metallic band and outer rubber s 0e, and

a entrance of any foreign matter. T e'flanges c which are nested in the grooves of the tread and shoe also add materially to effecting this result.

The detail illustrated in Fig. 3, shows one 6 of a clamping-bolts c rovided with projecting beads c, to whici heads is secured a guard-ring c, the urpose of which is to protect the sides of t 1e tire-casing from puncture, it being understood struction is carried out upon the opposite side not shown.

I claim:

IlSlIlg a one-piece tubular casing,

latter together with those 7 inner-face of 30 description it will be ainst the 5 that a similar con- 5 walls, a flattened split-base, and en outer hat have hereunto set my hand at Milwaukee, in bread extension; the cembinetion 01 a memh i the county of Milxmukee and State of Wis- 10 lie-baind fitted to the greedv extensien, a cousin in the presence of two witnesses.

5 ietallic clamping-rings fitted to the sides of l Mkhl 'l the shoe and. said flat treed extension, and. se- 3 -Witnesses: curing bolts connecting the rings. GEO. W. YOUNG,
